I think physics and intent aren't the same. In all hitting sports batspeed will peak at contact and drop off there steeply like that simply due to newtons laws

However still it can make sense to try to accelerate through contact because you don't want to slow down before contact which often happens if you don't finish the swing.
Keep in mind I'm not a high level table tennis player but I also coach baseball and it is there like that too, just like in golf or tennis which all teach to follow through and accelerate through contact even though technically it is not possible to accelerate through contact or even just maintain speed as the racket transfers energy in the collision.
